History of the McManus name

McManus comes from Mac Maghnusa, 'son of Magnus', a Norse personal name meaning great that entered Gaelic naming through Viking contact and became popular among Irish chieftains. The best-known sept were the Mag Uidhir (Maguire) kinsmen of County Fermanagh, where the McManus family were noted as scholars and scribes; the Annals of Ulster were compiled at their instigation on an island in Lough Erne. A separate branch existed in County Leitrim and Monaghan. The surname anglicised in several ways, including McManus and Manus, and it remains most common today in Fermanagh, Leitrim, Monaghan and Cavan, with a wide diaspora presence.
